University of Tokyo<\/strong><\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">Processes of fluid migration along subduction plate interfaces are important to understand the material and heat transportations, friction strength and rock fluid interactions along faults. We focused on syn-tectonic carbonaceous veins filling extensional cracks related to an underplating shear zone in Mugi m\u00e9lange in the Cretaceous Shimanto Belt. C-O isotope properties of geofluid were examined for the classified veins with normal or reverse stress regimes. The C-O isotope values have obvious positive correlations with its paleo-temperature from clumped isotope (\u039447). The variation in the isotopic values and paleo temperature of the geofluid indicates the existence of hot and external fluid migrated from deeper unit. Moreover, we also evaluated C-O isotope values of geofluids in the other settings with different depths. It showed a continuous C-O isotope evolution from deep (Higuchi serpentinite body) to shallow (~5 km of Mugi). Therefore, we could build a geofluid mixture model for its implication which reflects the migration of deep fluid from mantle wedge to shallow portion along a subduction plate interface.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color has-medium-font-size\">Ref.<br>Hosokawa and Hashimoto, 2022.&nbsp;<em>Scientific Report<\/em>. 12:14789<br>Okamoto et al., 2021.&nbsp;<em>Communication Earth &amp; Environment<\/em>. 2:151<br>Nishiyama et al., 2020.&nbsp;<em>Earth and Planetary Science Letters<\/em>. 538:116199<\/p>\n","protected":false},"excerpt":{"rendered":"<p>10\u670813\u65e5\u306bOnline\u3067\u7b2c\uff18\u56de\u5ca9\u77f3\u30fc\u6d41\u4f53\u30bb\u30df\u30ca\u30fc\u3092\u884c\u3044\u307e &#8230;<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"ngg_post_thumbnail":0,"footnotes":""},"categories":[99,1],"tags":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/geo.kankyo.tohoku.ac.jp\/gmel2\/index.php\/wp-json\/wp\/v2\/posts\/3258"}],"collection":[{"href":"https:\/\/geo.kankyo.tohoku.ac.jp\/gmel2\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/geo.kankyo.tohoku.ac.jp\/gmel2\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/geo.kankyo.tohoku.ac.jp\/gmel2\/index.php\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/geo.kankyo.tohoku.ac.jp\/gmel2\/index.php\/wp-json\/wp\/v2\/comments?post=3258"}],"version-history":[{"count":1,"href":"https:\/\/geo.kankyo.tohoku.ac.jp\/gmel2\/index.php\/wp-json\/wp\/v2\/posts\/3258\/revisions"}],"predecessor-version":[{"id":3259,"href":"https:\/\/geo.kankyo.tohoku.ac.jp\/gmel2\/index.php\/wp-json\/wp\/v2\/posts\/3258\/revisions\/3259"}],"wp:attachment":[{"href":"https:\/\/geo.kankyo.tohoku.ac.jp\/gmel2\/index.php\/wp-json\/wp\/v2\/media?parent=3258"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/geo.kankyo.tohoku.ac.jp\/gmel2\/index.php\/wp-json\/wp\/v2\/categories?post=3258"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/geo.kankyo.tohoku.ac.jp\/gmel2\/index.php\/wp-json\/wp\/v2\/tags?post=3258"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
